onkeyup="this.value = this.value.replace(/,/g,'.')" with php echo' '
提问by user2465936
In input field need to replace ,
with .

在输入字段中需要替换,
为.

With HTM such code is working onkeyup="this.value = this.value.replace(/,/g,'.')"
使用 HTM 这样的代码正在工作 onkeyup="this.value = this.value.replace(/,/g,'.')"
But need to use in php (with echo) like this:
但需要在 php 中使用(带回声),如下所示:
echo '<input type="text" name="amount_1" onkeyup="this.value = this.value.replace(/,/g,'.')" style="width:53px;"></input>';
With php does not work. If use this this.value.replace(/,/g,/./)
then ,
is replaced with /./
.
用 php 不起作用。如果使用它,this.value.replace(/,/g,/./)
则,
替换为/./
.
Tried (/,/g,"/./")
, (/,/g,/"."/)
, (/,/g,.)
nothing works (I mean ,
does not change to .
).
试过(/,/g,"/./")
,(/,/g,/"."/)
,(/,/g,.)
实在不行(我的意思是,
不改变.
)。
Any ideas?
有任何想法吗?

You have to escape the '
with a backslash in your PHP code.
您必须'
在 PHP 代码中使用反斜杠进行转义。
echo '<input type="text" name="amount_1" onkeyup="this.value = this.value.replace(/,/g,\'.\')" style="width:53px;"></input>';
Otherwise you are cuting your string into to pices an put it together with the point.
否则,您将把您的绳子切成小块并将其与尖端放在一起。
